The MJ8-POE is designed to protect sensitive data-processing equipment
connected to a POE (Power over Ethernet) network from transient
overvoltages.
The MJ8-POE surge protector is deployed in signal network applications
with data transmission speeds of 100 and 1000 Mbps.
The surge protector is housed in a shielded enclosure with high quality
RJ45 shielded jacks.
The transient protection circuit is based on high energy gas discharge
tubes (GDT) and a network of fast response silicon avalanche diodes
(SAD) to achieve sharp clamping of very large surge events.
